ELECTRO-COAT ADHESION LAYER WITH A SILOXANE TOP COAT

摘要

Described is a method of coating a metallic substrate comprising: providing a metallic substrate; applying an electrocoating composition by a cathodic electrocoating process to the substrate; and applying to the electrocoated substrate an aqueous coating composition comprised of a siloxane material. Also described is the product produced by the process having improved hardness, adhesion, corrosion resistance, abrasion resistance and appearance.
